Be sure that the “pre-supposed” utilities are
installed. Section 6
elaborates.

If you have any problem when building or installing the
Glasgow tools, please check the “known pitfalls” (Section 11). Also check the FAQ for the
version you're building, which is part of the User's Guide and
available on the GHC web
site.

If you feel there is still some shortcoming in our
procedure or instructions, please report it.
